Ok here's a Continental Europe one so I could get down to 100K Population. However, only the BLUE SHADED countries included...so it's basically West & Central Continental Europe. SEE NOTES BELOW MAP

I removed countries starting east until I was down to under 300 cities. So the included countries are in BLUE - yes I KNOW I didn't highlight every single area of each country but you get the idea - basically Czech/Slovakia/Slovenia/Austria westward INCLUDING European islands of Italy & Spain. Was not able to include all the alternative spellings for some cities (mostly German) due to a limit on characters in the answer field - included what I could - also for this reason a handful (about 5) of some less known cities will fill in early as I abbreviated them in the answer field. 28 cities are not within 100km of another - marked as always with a "*".
